Quartiles are values that divide a data table (or part of it) into four groups containing an approximately equal number of observations. The total volume is divided into four equal parts: 25%, 50%, 75% 100%.

The first quartile (or lower quartile) Q1 is defined as a value containing an f-value of 0.25. This is the same as the twenty-fifth percentile. The F-value of the third quartile (or upper quartile) Q3 is 0.75. The interquartile range IQR is defined as Q3 – Q1.
